Wind Could Meet 20% Of U.S. Electricity By 2030

The Department of Energy (DOE) published a major report looking at the viability of scaling up wind power in the United States. Wind power now makes up 4.5 percent of electricity generation in the United States, with 65 gigawatts located across 39 states.

Doubters of wind power – and renewables in general – cite a litany of reasons for why renewables cannot meet the needs of a modern 21st century industrial economy. Opponents argue that wind is too expensive and will raise electricity rates, or that the wind does not blow all the time, or that it cannot power heavy manufacturing.

The Energy Department conducted an economic study that looked at what would happen if wind power captured a rising share of the electric power market. And it concluded that wind passes all the necessary tests. First, it may only contribute to a 1 percent increase in electricity rates over the next 15 years, but those costs could then flip into savings, dropping by 2 percent through 2050.

Moreover, not only would scaling up wind have a negligible impact on electricity prices, but by reducing demand for natural gas to burn electricity, wind would lower natural gas prices, thereby creating big savings for uses of natural gas other than for electricity. Wind would save $280 billion through lower natural gas prices.

Another complaint about wind is that it can only be constructed in windy areas – in other words, the Great Plains. A band running from Texas to North Dakota is indeed the windiest section of the country, but the problem with that is that very few people live in wind-swept areas of South Dakota, Wyoming, or the panhandle of Texas, for example. But DOE finds that innovation in wind equipment – such as larger towers and blades that reduce the cost of generation – allow wind to spread well beyond these traditional windy areas. For example, increasing heights to 140 meters can allow wind to become viable across three times the amount of land space compared to 2008. Or, put more simply, wind can now be profitably built in Alabama, Florida, Georgia, Louisiana, Minnesota, Virginia, North and South Carolina, and several more states.

However, not all is rosy. Wind still faces stiff competition from natural gas as well as flat electricity demand. That is hurting investment and causing hesitation in the industry. Major improvements in technology, supply chain management, reliability, as well as a large build out in electric transmission capacity will be needed in order for wind to succeed over the long-term, conditions which are not guaranteed.

Not only do windmills kill thousands of endangered birds each year, they also are an ugly eyesore. If these monstrosities were used to pump oil or gas, the left would be screaming "visual pollution"......

There is only one argument to prove the 20% claim a bit bogus: The experience in Germany (or even better) Denmark. Denmark is loaded with windmills It may claim a nominal wind generation of about 25%, but upon review of their own figures it becomes obvious that such a percentage is feasible only because Denmark "dumps" their wind power onto Norway's hydro plants and imports either hydro power or nuclear power (from Sweden), or coal power from Germany. That is a "sell low - buy high" strategy that has led Denmark having the highest cost of electricity in Euroland. Denmark's green trick is only made possible from its small size relative to its neighbors and Norway's spare hydro capacity. Germany is doing the same in a much grander scale. It shows 7-8% nominal wind contribution but the fine print shows "exports" to French and Swiss hydro plants and unsolicited power exports to Poland and the Czech Republic. Germany has the second highest cost in Europe, in spite of coal and nuclear capacity. Will Canada play the role of Norway? Doubtful, it is not big enough, never mind willing. Wind is limited to a max 4-5-6% power substitution as demonstrated by EON as early as 2005. Unless if we like the looks and put them up for aesthetic purposes...
